  • the present invention relates to a foamable oral, dental care and tooth cleaning composition which is particularly suitable for use in tooth cleaning and care by means of a tooth brushing device for the simultaneous cleaning of several, preferably all, teeth of a user. Due to its low viscosity, the composition can be applied and distributed evenly, quickly and efficiently on the mouth insert of the toothbrush device.
  • the composition according to the invention expands to a briefly stable foam with good adhesiveness on the mouth insert, but which can then be liquefied again. This significantly simplifies handling. Nevertheless, a very good and gentle cleaning of the teeth and gums is possible.
  • the present invention further relates to the use of the foamable composition in a method for the simultaneous cleaning of several, preferably all teeth by means of the tooth brushing device.
  • the present invention provides a system consisting of the dental care and cleaning composition of the invention and a dispenser. With the help of this system the composition in the
  • oral and dental care products are in paste or cream form. They have a viscosity of 60,000 to 80,000 mPas (millipascal seconds; measured at 20 ° C) and are made from tubes or standing containers by manually compressing the Dispensed container on the brush head of a toothbrush.
  • the usual application amounts are 1 to 2 ml per use.
  • oral and dental care products are available in gel form with a viscosity of 10,000 to 70,000 mPas (at 20 ° C).
  • an amount of 1 to 2 ml is applied to the brush head of a toothbrush by applying pressure to the dispenser container.
  • a toothpaste with a relatively low viscosity - in other words, a liquid or liquid toothpaste - is in the
  • EP 2 813 214 A1 This composition has been formulated to enable stable incorporation of amine fluorides, but still be sufficiently viscous to be able to be applied to the brush heads of conventional or electric toothbrushes.
  • a tooth cleaning agent foaming after being dispensed from a storage container is disclosed in EP 1 257 250 B1.
  • This composition is also formulated for use with conventional toothbrushes and therefore has a viscosity of more than 30,000 mPas.
  • the present invention is not directed to the application of the oral and dental care and cleaning composition with a conventional manual toothbrush or a conventional electric toothbrush. Rather, there are more recent developments in the field of tooth cleaning, in which no longer the usual brush heads are used, but instead several or all of the user's teeth can be cleaned simultaneously by means of a mouth insert.
  • These mouth inserts are at least roughly, preferably individually, adapted to the dentition and jaw shape of a user and are able, by a motor to vibrate, to clean several or even all teeth at the same time.
  • Corresponding tooth cleaning systems are disclosed, for example, in DE 10 2015 109891 A1, WO 2009/137671 A1 or WO 2015/003681 A1.
  • the dosage forms of tooth cleaning and care products known in the prior art such as toothpastes, toothpastes or tooth gels, but also the known foams, are unsuitable.
  • the highly viscous products would have to be spread with a brush or spatula on the cleaning surfaces of the mouth inserts, taking into account the high viscosity of conventional toothpastes,
  • Toothpastes or gels make an even distribution almost impossible. At the same time, the amount of cream, paste or gel to be used would be approx.
  • a diluted toothpaste for example, does not adhere stably enough to the mouth inserts, especially in the case of an upside-down position, and would therefore run out of the inserts before they can be inserted into the mouth.
  • the foams known from the prior art also do not meet the requirement profile for such a tooth cleaning composition.
  • One reason for this is that the known foams are too stable and therefore cannot disintegrate sufficiently quickly or can be crushed by the user's teeth.
  • the high foam stability is disadvantageous for several reasons. On the one hand, such a stable foam swells out of the mouth inserts for the most part, which is undesirable and also means a loss of active substances and thus a reduced cleaning effect.
  • the foam remaining on the mouth insert, i.e. not displaced by the teeth still contains many air bubbles, which make the transmission of the vibrations of the motor difficult or reduce, which ultimately has a negative effect on the cleaning performance.
  • the formulations must ensure a stable dispersion of the cleaning agents in the composition. This is the only way to ensure that they are evenly distributed in the mouth inserts and that all teeth can be cleaned gently and efficiently.
  • the compositions must also meet the other requirements
  • the present invention relates, in a first aspect, to a dental care and cleaning composition for use in a method of

  • the mouth insert is formed in one piece, that is to say the mouth insert is designed in such a way that it is suitable for simultaneously holding the teeth of the upper and the teeth of the lower jaw (see FIG. 1).
  • the teeth are located on the sides of the mouth insert facing away from one another or open in opposite directions.
  • the toothbrushing device can contain several, preferably two, mouth inserts, the first mouth insert being designed to hold the teeth of the upper jaw and the second mouth insert being designed to hold the teeth of the lower jaw.
  • the tooth brushing device can be designed such that it only has one
  • Has mouth insert which is designed only to accommodate the teeth of a jaw, but is designed so flexibly that it can adapt both to the teeth of the upper jaw and to the teeth of the lower jaw. In such a case, the teeth row of one jaw and then the teeth row of the other jaw would be cleaned at different times. Still further alternatively, the mouth insert or can
  • Mouth inserts can be designed in such a way that they are each designed to receive tooth areas of the upper jaw and / or the lower jaw, the tooth areas being formed by teeth lying next to one another in the jaw, for example the molars or the incisors. For simultaneous tooth cleaning, several such mouth inserts are then used at the same time, which are to be selected so that all teeth of the upper and / or lower jaw are picked up. Alternatively, the All teeth can also be cleaned at different times. Preferred configurations of the mouth inserts are described in detail below, also with reference to FIGS. 1 to 5. All of these mouth inserts are particularly suitable for the administration of the dental care and cleaning composition according to the first aspect of the invention.

At the same time means that the mouth insert or mouth inserts are in contact with and clean all teeth to be cleaned at a time TI.
  • the brush head of a conventional manual or electric toothbrush comes into contact with the teeth to be cleaned one after the other. This not only increases the amount of time spent cleaning, but also always involves the risk that not all teeth are cleaned with the same care and intensity.
  • the essential components of the composition used according to the invention in the specified proportion ranges make it possible to provide a low-viscosity composition.
  • An essential component of the composition is glycerin. It was basically known in the prior art that glycerin can be used as a possible humectant in tooth cleaning and care products. The relevant prior art has given the skilled worker a large range of other possible humectants at the same time. Humectants are usually added to dental care and cleaning products to prevent the composition from drying out. It has now surprisingly been found that glycerin, when used in a high proportion, can be used as a matrix former for the other ingredients and as a stabilizer for the composition, in particular as a short-term stabilizer for a foam obtained from the composition. The advantageous multiple use of glycerin was surprising.
  • the glycerin lowers the surface tension of the water also contained in the composition with a relatively high proportion.
  • this has the consequence that the stability of a foam obtained from the composition is influenced in such a way that for the time window of the application of the composition onto the mouth insert or the

  • this time window is usually in a range of a few seconds.

Abstract

La présente invention concerne des compositions pouvant mousser destinées aux soins dentaires et leur utilisation pour nettoyer et prendre soin des dents et de la bouche. Préparée sous forme de mousse ou d'aérosol, la composition peut être appliquée uniformément, rapidement et efficacement sur des inserts buccaux, des prothèses amovibles et autres dispositifs servant à nettoyer simultanément plusieurs dents ou toutes les dents. La manipulation est sensiblement simplifiée.
